I remember in my, "old" Girl Scout days, how we made portable stoves. We would use a juice can and use a bottle opener to punch holes around the top (open end) then place it over a tuna can that had tightly wound up corrugated cardboard place in it. We then poured melted paraffin over the cardboard. We would then light the cardboard/paraffin. This would be our heat source. Next we would place the juice can over the tuna can. The top of the juice can would be our cooking surface. Talk about a smoky mess!! This new device looks like a bit of heaven. Besides, there's not juice cans anymore (I know the industrial sized cans are out there); plus the tuna cans are not the same quality they were back then. I think we fried bacon on the thing and tried to cook an egg. Of course, this was quite some time ago. I don't think the things tasted very good either. Wow, I hadn't thought about that in ??? years. Thank you, Stanley for the walk down memory lane!
